The Investigation of the log(ft) Values for the Allowed Gamow-Teller Transitions of Some Deformed Nuclei

The log(ft) values of allowed β± decay between odd-A nuclei for 125 < A < 180 mass region are investigated. Single particle energies and wave functions are calculated by making use of a deformed Woods-Saxon potential. The calculations are performed in the framework of proton-neutron quasi particle random phase approximation (QRPA) including the schematic residual spin-isospin interaction among the nucleons in the particle hole channel. The calculations indicated that the results obtained through using the χGT=5.2/A0.7 are more in agreement with experimental observations
